Seems like a waste for large IOs (sorry for Sagi> diverging from the subject) The assumption was that there would be a 1:1 mapping between the number of data buffers and the metadata ditto. But nothing says that a data iovec entry is limited in size to a single sector. The other option to have a single iovec at the end representing the metadata for all data buffers. I think there are valid use cases for either approach and we may end up having to support both via a flag. -- Martin K.
